C. Well devloped uterus filled with eggs
D. Become dead .

Answer

To determine when a proglottid of Taenia is referred to as "gravid," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Proglottids**: Proglottids are segments of the body of a tapeworm, such as Taenia. They are formed as the worm grows and can be categorized based on their developmental stage.

2. **Identifying Gravid Proglottids**: A proglottid is termed "gravid" when it is in the final stage of development. This means it is fully mature and ready for reproduction.

3. **Characteristics of Gravid Proglottids**: Gravid proglottids are characterized by the presence of a well-developed uterus. This uterus is filled with fertilized eggs, indicating that the proglottid has completed its reproductive function.

4. **Absence of Reproductive Organs**: In contrast to younger proglottids, which contain reproductive organs, gravid proglottids do not have these organs. Instead, they focus on the storage and transport of fertilized eggs.

5. **Conclusion**: Therefore, a proglottid of Taenia is called "gravid" only if it has a well-developed uterus filled with fertilized eggs.

### Final Answer:
A proglottid of Taenia is called gravid only if it has a well-developed uterus filled with fertilized eggs.
